// .NAME vtkPVUpdateSuppressor - prevents propagation of update
|
|
// .SECTION Description
|
|
// vtkPVUpdateSuppressor now uses the vtkProcessModule singleton to set up the
|
|
// default values for UpdateNumberOfPieces and UpdatePiece, so we no longer have
|
|
// to set the default values (in most cases).
